liquidambar styraciflua - to prune or not to prune

Hi All,

I recently blind purchased some 200/250cm liquidambar styraciflua. I was expecting to receive "trees" which would have had at least the bottom 60cm or more clear stemmed.

What I received were plants with branches remaining right from the base. Varying branch thickness and unfortunately varying degrees of balance have left me with a conundrum.

At a quick glance I thought it might be nice to plant them as they are however my original plan was to eventually have clear stems of approximately 150 - 175 cm. They are being planted along a 5 foot garden fence.

My fear when attempting to prune them (notwithstanding that time is running out if not already run out to prune this season) is that I'll be left with gnarly stems as some of the side branches are already rather strong. 

Any suggestions either way would welcomed

    Why not call the nursery you bought them from? they should know the answer.

    They are beautiful trees, my neighbour planted one about 10 years ago.
    Do bear in mind that in time they will eventually get to 60-70ft high and their extensive root system will spread about the same distance and can cause damage to buildings.

    They are big trees! 
    You wanted just the stem against the fence, then all the branches as screening above the fence, yes? 
    I think if that’s what you want, then do it, but possibly not right now. Plant them and get them established and take a measured approach to the lower branches at the right time, and when they have more top growth.

    I would leave the bottom branches on for now
    Plant your trees ...then next winter, once they have developed  new roots, remove the bottom branches.
    Make sure you give each one plenty of space.

  • You can trim the straggly branches off now if you wish. I'd stake them for the first two years, they can rock a bit in high winds. 
    As you have so many are they "fastigiata" or "slender silhouette"? These will grow at a moderate pace and 'eventually' get to about 40 feet. Don't worry about foundation damage..well not yet.. potential foundation damage from trees tends be over estimated in most cases.
  • Hi All,

    Many thanks for taking the time to provide some feedback on my query. I purchased them from a distributor who wouldn't have the time nor expertise to help me with them to be honest.

    I am going to strip the bottom 45/50 cm and then lightly prune the branches on the next 30 cm I think. I'll revisit the issue then next winter.

    I'm not sure which specific variety they are. They will get big but I'm hoping to keep manners on them for as long as possible

    Does anyone know how easy or hard it would be to attempt a pleaching of sorts with these trees?
